Smiths. Misc. Coll., vol. 61, No. 21, 1913, p. 7. 

 No. 21. <£ Toembang Maroewe, Central Borneo, Sept. 1915. 



This species is easily distinguished form the other Bornean form viz. Arctoga- 

 lidia stigmatica Temm. by its smaller size. 



According to Miller it is most closely related to A. simplex from Linga and 

 Singkep and to A. inornata from the Natuna Islands. 



The general colour above is greyish brown, darker on the head. Along the 

 back a faint median blackish brown stripe running down to the base of the tail. 

 Under parts of the body cream buff (Ridgway pl. 30), fairly in contrast with the 

 colour of the sides. Chin, throat and upper breast like the upper parts of the body,
